The North Rillito Interceptor (NRI) project

The North Rillito Interceptor (NRI) project is approximately 10 miles long. The NRI is a large diameter pipeline that transports wastewater from the City’s far east side in the Woodland Road and Bear Canyon area, along the north bank of the Tanque Verde Creek and Rillito River, to the Ina Road Wastewater Treatment Facility -- which serves a major portion of northern and eastern Tucson.

Although there are no immediate plans to increase the NRI’s capacity due to limited density growth, the RWRD must comply with U.S. E.P.A. guidelines relating to wastewater system capacity, management, operations and maintenance and to minimizing the number of sewer overflows.

The North Rillito Interceptor Relief project

The North Rillito Interceptor Relief project will connect the NRI and the SRI in the Columbus Boulevard area. Ultimately this new connection allows the RWRD to convey 10 million gallons of wastewater a day, reducing the potential for sewer overflows and ensuring compliance with U.S.E.P.A. guidelines for capacity, management, operations and maintenance.

Construction of the new NRI Relief facilities requires heavy civil work related to excavation required for structures and the sewer siphon from the north bank to the south bank of the Rillito River.

22nd Street Sewer Augmentation

Pima County and its contractor, KE&G Construction Inc., will begin work on the 22nd Street Sewer Augmentation project which extends from Alvernon Way to Swan Road. This work is necessary because the existing pipe is at or near its maximum flow capacities. This project will install new sewer along 22nd Street from Alvernon Way to Swan Road, increasing sewer volume and improving the lifespan of the sewer infrastructure in the area.
